FINISHING
(1) Insulate between pipes.
●
For rear, right, and bottom piping, overlap the connection pipe
heat insulation and indoor unit pipe heat insulation and bind
them with vinyl tape so that there is no gap.
●
For left and left rear piping, butt the connection pipe heat insula-
tion and indoor unit pipe heat insulation together and bind them
with and vinyl tape so that there is no gap.
●
For left and left rear piping, wrap the area which accommodates
the rear piping housing section with cloth tape.
●
For left and left rear piping, bind the connection cord to the top
of the pipe with vinyl tape.
●
For left and left rear piping, bundle the piping and drain hose
together by wrapping them with cloth tape over the range within
which they fit into the rear piping housing section.
(2) Temporarily fasten the connection cord along the connection pipe
with vinyl tape. (Wrap to about 1/3 the width of the tape from the
bottom of the pipe so that water does not enter.)
(3) Fasten the connection pipe to the outside wall with a saddle, etc.
(4) Fill the gap between the outside wall pipe hole and the pipe with
sealer so that rain water and wind cannot blow in.
(5) Fasten the drain hose to the outside wall, etc.

CUSTOMER GUIDANCE
CAUTION
(1) The power source capacity must be the sum of
the air conditioner current and the current of other
electrical appliances. When the current contracted
capacity is insufficient, change the contracted ca-
pacity.
(2) When the voltage is low and the air conditioner is
difficult to start, contact the power company the
voltage raised.
Explain the following to the customer in accordance with the operat-
ing manual:
(1) Starting and stopping method, operation switching, temperature
adjustment, timer, air flow switching, and other remote control unit
operations.
(2) Air filter removal and cleaning, and how to use the air louvers.

the insulation to about 15/16" (25 mm) to expose the solid wire.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
board.
(3) Using pliers, bend the solid wire to form a loop suitable for the termi-
nal screw.
(4) Shape the loop wire properly, place it on the terminal board and
tighten securely with the terminal screw using a screwdriver.
B. For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip
the insulation to about 3/8" (10 mm) to expose the strand wiring.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
board.
(3) Using a round terminal fastener or pliers, securely clamp a round
terminal to each stripped wire end.

WARNING
(1) The rated voltage of this product is 208/230 V AC
60 Hz.
(2) Before turning on the power, check if the voltage
is within the 208 V-10% to 230V+10% range.
(3) Always use a special branch circuit and install a
special receptacle to supply power to the room
air conditioner.
(4) Use a circuit breaker and receptacle matched to
the capacity of the air conditioner.
(5) Do not extend the power cord.
(6) Perform wiring work in accordance with stand-
ards so that the air conditioner can be operated
safely and positively.
(7) Install a leakage circuit breaker in accordance with
the related laws and regulations and electric com-
pany standards.
PUMP DOWN OPERATION (FORCED COOLING OPERATION)
To avoid discharging refrigerant into the atmosphere at the time of relocation or disposal, recover refrigerant by doing the cooling operation or
forced cooling operation according to the following procedure. (When the cooling operation cannot start in winter, and so on, start the forced
cooling operation.)
(1) Do the air purging of the charge hose by connecting the charging hose of gauge manifold to the charging port of 3 way valve and opening the
low-pressure valve slightly.
(2) Close the valve stem of 2 way valve completely.
(3) Start the cooling operation or following forced cooling operation.
When using the remote control unit
Press the TEST RUN button after starting the cooling operation by the remote control unit.
The operation indicator lamp and timer indicator lamp will begin to flash simultaneously during test run.
When using the MANUAL AUTO button of the indoor unit (The remote control unit is lost, and so on.)
Keep on pressing the MANUAL AUTO button of the indoor unit for more than 10 seconds.
(The forced cooling operation cannot start if the MANUAL AUTO button is not kept on pressing for more than 10 seconds.)
(4) Close the valve stem of 3 way valve when the reading on the compound pressure gage becomes 0.05~0 MPa (0.5~0 kg/cm
2
).
(5) Stop the operation.
• Press the START/STOP button of the remote control unit to stop the operation.
• Press the MANUAL AUTO button when stopping the operation from indoor unit side.
(It is not necessary to press on keeping for more than 10 seconds.)
CAUTION
During the pump-down operation, make sure that the compressor is turned off before you remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2 way or 3 way valve open. This may cause abnormal
pressure in the refrigeration cycle that leads to breakage and even injury.
REMOTE CONTROL UNIT INSTALLATION
CAUTION
(1) Check that the indoor unit correctly receives the
signal from the remote control unit, then install
the remote control unit holder.
(2) Select the remote control unit holder selection
site by paying careful attention to the following:
Avoid places in direct sunlight.
Select a place that will not be affected by the heat
from a stove, etc.
1. REMOTE CONTROL UNIT HOLDER INSTALLATION
•
Install the remote control unit with a distance of 23 ft(7
m) between the remote control unit and the photocell
as the criteria. However, when installing the remote con-
trol unit, check that it operates positively.
•
Install the remote control unit holder to a wall, pillar,
etc. with the tapping screw (Fig.20).

IMPORTANT
This product has been designed and manufactured to meet ENERGY STAR criteria for energy efficiency when matched
with appropriate coil components. However, proper refrigerant charge and proper air flow are critical to achieve rated
capacity and efficiency. Installation of this product should follow the manufacturer's refrigerant charging and air flow
instructions. Failure to confirm proper charge and air flow may reduce energy efficiency and shorten equipment life.
